I agree with many of the other posters. It sounds like they are strictly speaking about the "best deal" as in the "best price" per pound, without consulting whether the food is of a human grade or barrel scraps. I barely read, let alone put stock into anything that is put out by non-scientific authors. This past year alone, one of the big consumer companies posted on Comcast.net that cucumbers were a waste of space in a salad containing no valuable nutrients. Any first year nutritionist knows the complex nutrients that cucumbers offer. Which begs the question why?
Right now, many people who are in the field are afraid the the Codex Alimentarius is being directly influenced by uneducated governmental sources, but that is another battle.
